I have a skin problem. I took advise from different dermatologist but all diagnosed it differently some called it seboric dermatosis while other said is macular amyloidosis and one more doctor told me its keratosis. I dnt understand which is correct. Now problem is as described below some mini dots occurred at my back (shoulder) which later converted in black patches with severe itching. It all started 7 years back. Same mini dots spreading at my arm of both hand and chest which later converted into black patches. If I eat eggs or takes tea itching increased in affected area and mini red boils also comes at my chest and back. These mini red dots disappear after 3 to 4 dots. Skin in the affected area is very rough and itching all also continue till I take levocetirizine.
